>Description:
Documents using the `-offset string' function in mdoc will report
errors and fail to format in troff mode. The mdoc macro tries
to interpret `string' as a number to see if it matches the
`-offset xxn' variant. If the first character of string is not
numeric, groff reports an error.
>How-To-Repeat:
groff -man /usr/src/sbin/camcontrol/camcontrol.8 > /dev/null
reports:
/usr/src/sbin/camcontrol/camcontrol.8:549: warning: numeric expression expected (got `f')
/usr/src/sbin/camcontrol/camcontrol.8:561: warning: numeric expression expected (got `f')
/usr/src/sbin/camcontrol/camcontrol.8:570: warning: numeric expression expected (got `f')
/usr/src/sbin/camcontrol/camcontrol.8:580: warning: numeric expression expected (got `f')
/usr/src/sbin/camcontrol/camcontrol.8:601: warning: numeric expression expected (got `f')
/usr/src/sbin/camcontrol/camcontrol.8:607: warning: numeric expression expected (got `f')
/usr/src/sbin/camcontrol/camcontrol.8:614: warning: numeric expression expected (got `f')
/usr/src/sbin/camcontrol/camcontrol.8:672: warning: numeric expression expected (got `f')
>Fix:
Inserting a zero before the interpolated string silences the
error and appears to generate correct output.
